SPECIFICATION forming part of Letters Patent No. 407,048, dated July 16, 1889.

Application led March 19, 1889. Serial No. 303,852. (No model.)

To all whom it may concern.-

Be it known that we, VILLIAM VILCOX and WILLIAM ALARIC WILcoX, citizens of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain Anew and useful Iniprovements in Evaporators; and We do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to evaporators, and has for its object improvements on the constructions shown in our application filed .l anuary 28, 1887, Serial No. 225,815.

The invention will be hereinafter described, and particularly pointed out in the claims.

In the accompanying` drawings, which forni part of this specification, Figure 1 represents a plan view of our improved evaporator; Fig. 2, a vertical longitudinal section of the same; Fig. 3, a vertical transversesection, on an enlarged sc ale, on the line 0c, Fig. 2; and Fig.

v 4, a perspective view of the heater detached.

Reference being had to the drawings and the letters thereon, A indicates an arch, the construction of which is described and claimed in the application to which reference has been made, except the features which cooperate with our improved heater herewith shown. The arch is provided with an extension B at its rear end, which projects beyond the heater C when in position for heating Sirup, as shown in Figs. 2 in full lines, and forms a support for the heater when it is drawn out of the uptake D, as shown by vdotted lines in said figure. The uptake crosses the arch near the rear end and is secured thereto, and the sides a Z) and the front end c thereof inclose the horizontal extension E of the heater and cause the gases of the combustible material in the furnace to pass through the vertical dues (l in said extension and impart their heat to the juice surrounding the flues in the heater.' The uptake is provided with a suitable chimney or stack (not shown) to carry off smoke and is open at its rear end, so that the heaters C may be withdrawn and a direct draft produced through the uptake when the run or charge of juice is being finished in the evaporatingpan. When the heater C is Withdrawn from the uptake D, it rests upon the extension B of the arch, and the front end of the extension E forms the rear wall of the uptake, as shown in dotted lines in Fig. 2, and presents sufficient surface to the heated gases passing on to the stack to keep the juice in the heater hot until it has all been Worked through the evaporating-pan. The juice flows from a suitable tank into the heater and from the heater it flows through a pipe e into the receivingcompartment f of the evaporating-pan F, Where the supply is regulated automatically by a valve g, controlled by a float h.

The automatic supply-valve is fully shown, described, and claimed. in our application iiled September 8, 1887, Serial No. 249,137.

The supply of juice from a tank to the heater may be controlled by a duplicate of the valve shown in the receiving-compartment f by placing it in the heater.

In finishing a run or charge of juice, or at the close of the operation of evaporating, the juice in the vertical extension G of the heater C below the level of the pipe e, where it connects with the heater, is withdrawn through a faucet t' and poured into the compartment f of the evaporating-pan.

The boiling-compartment of the pan is designated by the letter 7s and the finishing-compartment by Z. The latter compartment is provided with a transverse depression fm, which is inclined toward the discharge side thereof and the valve n for the purpose of drawing the sirup therefrom.

The juice iiows from one compartment in the pan to another through suit-able openings (not shown) in the vertical partitions o, p, q, and yr from the receiving to the finishing compartment.

Having thus fully described our invention, what We claim isl. In an evaporator, the combination of an arch having an uptake provided with an open end, and aremovable heater having iiues and projecting into the uptake, substantially as described.

2. In an evaporator, the combination of a removable heater provided with flues and an IOO removable heater having a horizontal ext-ension provided with a series of vertical iiues and a vertical extension in the rear thereof provided with a discharge-pipe near its upper end, and a valve for drawing off the contents below the discharge-pipe, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
